GLAZING MAGHIN E.

Application filed December 13, 1919. Serial No. 344,617.

To (IZZ whom it may (:01 (-er'n Be it known that I, Hans X. linnvnnsex, a citizen of the United States, residing at Vineland, in the county of Cumberland and State of New Jersey, have invented certain new and useful Improvements in Glazing Machines, of which the following is a specification.

The improvement of so-called glazing machines constitutes the subject-matter of the present invention, appliances of this style being used for smoothing or finishing the somewhat rough or sharp and jagged ends of glass tubes, rods, or similar bodies, by heating them until they become soft and more or less fused, and then permitting them to cool. The fused or partly melted glass in cooling and hardening becomes smooth, presenting a desired and proper finish.

One of the salient features of the machines.

embodying this invention, that is to say, one of the prime objects of the invention is the production of an apparatus of this character which is simple in structure and hence economical to construct, and which will perform the glazing operation with facility and dispatch Stated somewhat diiierently, one of the leading aims of the invention is the provision of aglazing machine of this type which shall have a large Working capacity and glaze one or both ends of tubes or rods in large quantities and with comparatively great rapidity. A further-purpose is the production of a machine of this character which is wholly automatic and continuous in main portion of the machine illustrated in Figure 1,

Figure?) is an enlargedvertical cross-sec tron on line 3 3 of Figure 1; and

Figure 4 is a similar vertical cross-section on line ;4 of Figure 1.

The machine comprises, as will be understood from the drawings which term a part of this specification, a main skeleton frame 10 standing on suitable supporting legs 11, 11, appropriately connected together, the frame including an elongated upper portion incorporating a pair of spaced, longitudinal side-bars 12 and 13 angleshape in cross-section. At one end, the appliance has a pair of bearings li and 15 for a crossshaft 16 driven in. a counter-clockwise direction, as the parts are viewed in Figure 1, from a lower drive-shaft 17 through suitable gearing 18, 19, shaft 17 being rotated from any convenient source of power, as by a pulley 20 and cooperating belt 21. The other end of the apparatus is supplied with a second parallel cross-shaft 22 revoluble in bearings 23 and 24 mounted on the lengthwise bars 12 and 13, these two parallel shafts being each supplied with a pair of sprocket-wheels 25, 25, 26, 26, co-acting with which is a pair of parallel relatively-long sprocket-chains 27, and 28 maintained undo proper tension by suitably-supported revoluble idler sprocketwheels 29'. As is illustrated, the sprocket- "hcels 25 and 26: e keyed to their respective shafts but are capable of adjustmentlengthwise the same as are also the toothed wheels 29 on their shaft 30.

Along the top of the machine the upper stretches or lengths of these sprocket or conveyor chains ride or travel on the flat, horizontal upper surfaces of a pair of tracks 31 and 32 mounted on appropriately-bent brackets or supporting-arms fastened to the frame side-bars 1.2 and 13. Thus such supported parts or active sections of the chains are not permitted to sag and are compelled to travel in straight, horizontal, paral lcl lines. The links of such conveyor chains arc equipped with outstanding arms of fingers 3% having forwardly-bent outer end portions for a purpose hereinafter indi cated.

Also mounted on and at the outer sides of the tracks 31 and 32 are a pair of asbestos or other suitable heat-proof rails 36,37, the

' former at the right hand portion of the ma chine having an elevated or vertically-deeper part 38 with a horizontal top edge,- the rail 37 at the left-hand partof the machine having a similar elevated portion 39. The tubes 40 to be glazed roll along on the upper edges of these asbestos rails under the feeding action of the conveyor and the purpose of the elevated portions is to cause the tubes to tilt or incline in opposite directions crosswise the machine, that is, lengthwise the tubes, as illustrated in Figures 3 and 4 for a purpose hereinafter described.

Just outside of the elevated rail portion 38 and mounted adjustably on brackets 41 capable of regulation as to position is an elongated gas-burner with a long flame 43 issuing from the relatively-lengthy jet-opening 49 of the burner parallel to the rail, the burner being covered by a suitable protec tive hood or shield 44. Opposite. this burner and outside of or beyond the other asbestos rail 37 a flat, vertically-disposed, metal guide or gauge plate 45 is carried on adjustable stationary brackets 46, mounted on the frame-bar 13. I

In similar manner outside of the deep portion 39 of the asbestos rail 37 a like burner 47 is adjustably mounted on brackets 48 carried by the frame bar 13, the burner having a long jet opening 49 from which issues a long narrow gas flame 50 covered by a curved shield or hood 51. Opposite such burner and outside of or beyond the rail 36 and parallel to the jet opening of the burner, I provide a second guide or auge plate 52 carried on the frame sidebar 12 by adjustable brackets 53, 53, one end of the plate 52 desirably being flared or bent outwardly at 54 so as not to conflict with the approaching tubes.

At one end of the machine a supply-magazine 55 (Figures 1 and 2) is positioned from which the tubes or rods to be glazed are delivered one at a time in any approved manner to the endless chain conveyor, and at the other end of the machine a storage compartment or magazine 56 is employed into which the finished or glazed tubes or rods are delivered in succession, retrograde movement or backward rolling of the delivered tubes being prevented by a pivotedcatch or retainer 57 of any appropriate design.

The operation of the appliance occurs practically as follows:

The transverselyraligned pairs of curved or bent fingers 34, 35, of the conveyor remove the tubes to be treated individually in succession from the supply-magazine 55 in a well understood way, the tubes being caused to roll along on the top edges of the parallel asbestos rails by the conveyor-fingers or lugs which engage them. Inasmuch as the upper edge of the rail portion 38 is higher than the corresponding edge or the top surface of the companion rail 37, the tubes while traveling or rolling along with 1 ,evsnvs one end above and in register with the gasflame 43, as shown in Figure 3, are tilted, thereby tending to maintain the opposite ends of the tubes in contact with the face of the guide or gauge plate 45, the position or'forwardly-bent end portion 35 of the Y corresponding conveyor-finger 34 which results in causing that end of the tube to be slightly in advance of the other end of the tube with which the straight portion of the complementary finger 34 co-acts. This is fully shown in Figure 2. Such diagonal disposition of the tubes coupled with their rolling action on the rails also tends to keep their unheated ends in proper contact with the guide members 45. By thus rolling along on the rails, one end of each tube is uniformly heated throughout its circumference and glazed or smoothed as soon as it cools. Of course, the speed of travel. of the tubes, the length of the burner-jet, the ad justment of the position and size of the flame, are all proper to secure the required,

but not excessive, heating of the tube ends.

After eachtubexleaves the burner flame 43 and the positioning plate 45, for a time it rolls in horizontal relation and in a position directly crosswise the machine as shown in Figure 2 on the rails 36 and 37 of equal height and at this time it is fed along by the straight portions of both conveyor fingers. During this short period of travel the heated ends of the tubes cool sufficiently so that soon afterward they may bear against the second guide-plate 52.

After passing this central cooling portion of the apparatus, the tubes in sequence travel upon to the raised portion 39 of the rail 37 which tilts them in the opposite direction, as shown in Figure 4, and at the same time, by reason of their one end being raised into co-operative relation with the curved ends of the conveyor-fingers, they are positioned slightly diagonally in a direction the opposite of that which they previously assumed (see Figure 2). Both of these displacements from a straight hori zontal crosswise position keep their lower ends in proper contact with the gauge-platc 52 and as the tubes roll along their opposite ends are in suitable register with the flame of the burner 47 and are heated and glazed as will be readily understood.

the entrance of the storage compartment or said heating means, scribed.

matically rises and descends as the tubes.

pass beneath it during their entrance into the storage compartment or magazine.

From time to time, the tubes or rods, as

the case may be, with smoothed, finished, glazed ends may be removed from the compartment 56 and, of course, the supply of tubes to be treated must be maintained in the magazine 55, otherwise the wnole operation of the machine is automatic and continuous and the tubes or rods are glazed with rapidity and effectiveness. 7 All of the parts of the appliance are adjustable so that tubes or rods of diifercnt dimensions may be glazed in this machine by merely effecting the proper position of the various elements of the mechanism.

Merely because one preferred embodiment only of the invention has been illustrated and described, is not to be-taken as the only way in which the invention may be incorporated in satisfactory physical form, because on quite the contrary, the invention is capable of a variety of successful embodiments varying more or less in structural features, but all embodying the main underlying principles of structure and mode of operation.
